The billiard balls without replacement.

Let's say there are 10 billiard balls 5 red and 5 blue.

If you pick a blue ball on the first pick you had a 5/10 chance

Now your chances of getting a red are only 5/9.

What happened on the first pick affects what happens on the second (making it dependent)
